My friends and I (5 people) stayed at Tony's place for 5 days. The place is lovely, very modern and clean. The view from the master bedroom is gorgeous. He provided us 2 mobile wifi devices which was a wonderful surprise for us and we're very handy for us. The surrounding of the condo is also very beautiful, 24 hrs guarded. Very safe.
Location wise, it's about 3-5 mins walk from the phra ram 9 MRT station. From the MRT, you can exchange at Siam for BTS. Taxis are also cheap.
We love it there. Would recommend to others and would come back if going to Bangkok.
Tony also replies messages quite fast. He answered our travel questions when asked as well.
